HAIR CURLER Filed April 25, 1936 INVENTOR.

Patented May 24, 1938 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to hair curlers, and particularly to the typewherein a bar, arm, and band are cooperatingly hinged to allow curlingof the hair around the bar and arm, and retain it in curled state.

The principal object of the invention is to pro- Vide a conveniently andeconomically manufacturable, conveniently utilizable, efiicient, andimproved hair curling device of the above type.

Another object is to provide a hair curler of the above type withimproved means for positively and efiiciently engaging its hairretaining band to its hair curling bar, for improving the operation andresulting performance'of the hair curler.

Other objects and advantages will hereinafter appear.

In the accompanying drawing,-

Fig. 1 is a side elevation of the hair curler of this invention.

Fig. 2 is a cross-sectional plan view, showing the portion of the haircurler for engaging its hair retaining band to its hair curling bar.

Fig. 3 is a fragmentary plan view showing a modification of theimprovements illustrated in Fig. 2.

Fig. 4 is a fragmentary cross-sectional plan view, showing anothermodification of the improvements.

Fig. 5 is a cross-sectional side elevation of the improvements shown inFig. 4.

The hair curler I, Fig. 1, comprises a tubular bar 2, a concave arm 3,and a retaining band 4 preferably made of wire. Said bar, arm, and bandare hingedly connected to each other as shown at 5, whereby the bar,arm, and band are swingable relatively to each other about a com- `monaxis, as illustrated by the dot and dash lines. The bar 2 and arm 3 areprovided with finger-pieces 6, l, and a spring, as shown, bears againstsaid finger pieces, whereby the bar 2 and arm 3 lare normally impelledto bear pressingly against each other as shown, while when thefinger-pieces. '6, 'l are pressed toward each other the arm 3 is swungaway from the bar 2 to the position shown by the dash and dot lines.

The end portion 8 of the band 4 is formed straight and right angularlyto the bar 2, and it carries a device 9 wherewith to engage the band tothe arm, as required for the operation of the hair curler. Said deviceconsists of a spherical metallic shell IU mounted over and around theband-portion 8 and having relatively large openings ll that are coaxialwith the band portion. The shell l0 is filled with a body l2 of pliablerubber having a bore 13 constituting a bearing to render it revolubleabout the band-portion 8 which thus serves as an axle shaft for theentire device 9. On exerting any pressure by rim M upon the equatorialarea of the shell Il) it will be shifted eccentrically toward the shaftB, as shown by the dash and dot lines, Fig. 2, due to thecompressibility of the rubber body [2 therewithin, while upon release ofsuch pressure the shell IO will at once spring back to the normalcoaxial position shown, owing to the resiliency of its rubber body. Whenthe band 4 is swung away from the bar 2 the device 9 is in its normal orcoaxial position shown in Fig. 2, but when the band is swung toward thebar the equatorial portion of shell lil strikes the terminal rim |4 oftubular bar 2, which thereupon presses and actuates the shell to aposition eccentrically to the shaft 8 and successively causes the shellIU to spring back to normal coaxial state and to fall into and inlocking engagement with the terminal of bar 2, as shown in Fig. 1.Swinging of the band 4 out of alignment with the bar 2 will of courseproduce a reversal of the above described operation and a consequentdisengagement of the band from the bar. When utilizing this hair curler,the arm 3 is first disposed to the open inoperative position, shown bythe dash and dot lines, Fig. 1, the end of the hair is then placedbetween it and the bar 2, then said end is gripped by releasing the armto the spring-pressed position shown against the hair and bar 2, andthen the curling of the hair is continued around the closed arm and bar,after which the band 4 is swung into engagement With the bar to maintainthe hair in the curled condition as required.

According to the modification shown in Fig. 3, the engaging device Ba;consists of a spiro-helical wire spring 15, the terminals IE of whichform a bearing about the band-shaft portion 8 of the band 4, whereby thespring tuft l5, having the general outline ofV a spherical body, isrevoluble about the shaft 8 to and around which it is thus mounted. Whenswinging this band 4 into alignment with the bar 2 and away therefrom itwill engage with it and disengage therefrom in the manner describedabove in connection with the device 9, Figs. 1, 2.

In the modification shown in Figs. 4, 5, the engaging device 9b has ashell lil similar to that Shown in Fig. 2, which shell is filled with aflat metal spiral spring I 1, the inner terminal end IB of which forms abearing about the bandshaft portion 8 of the band 4 and its outermosthoop I 9 is fiared against the inner Wall of the shell ll), Whereby thelatter is revoluble about the shaft 8, and When the band li is swunginto cooperative alignment with the bar 2 this device 911 Will engagewith it in the above described manner and accordingly disengagetherefrom when the band is swung away.

Variations may be resorted to Within the scope of the invention, andportions of the improvements may be used Without others.

Having thus described my invention, I claim:-

l. A hair curler having the combination of a hair winding bar, a hairretaining band having. an end serving as an axle, said band and barbeing hinged to each other, a device carried by the said axle includinga shell, and a filler of rubber Within said shell being mounted on saidaxle to permit the shell to move in a motion of translation to aposition eccentrically to the axle and successively to a positionconcentrically with the axle for engaging with and disengaging from theend 'of said bar.

2. A hair curler having the combination of a hair Winding bar, a hairretaining band having an end serving as :in axle, said band and barbeing hinged to each other, a device carried by the said axle includinga shell, and a filler of elastic material within said shell beingmounted on said axle to permit the shell to move in a motion oftranslation to a position eccentrically to the axle and successiveiy toa position concentrically With the axle for engaging With anddisengaging from the end of said bar.

3. A hair curler having the combination of a hair Winding bar, a hairretaining band having an end serving as an axle, said band and bar beinghinged to each other, a device carried by the said axle including ashell, and a resilient member Within said shell being mounted on saidaxle offering resistance to compression upon the periphery of the shellto permit the shell to move in a motion of translation to a positioneccentrically to the axle and sucoessively to a position concentricallywith theV axle for engaging With and disengaging from the end of saidbar.
